The ISO 20502 standard provides a scratch test method for the determination of coating adhesion of fine ceramics, including advanced ceramics and advanced technical ceramics. By controlling the force and displacement parameters in the scratch test, the method quantitatively evaluates the adhesion performance of ceramic coatings to substrates and the interfacial bonding mass. This standard is suitable for a variety of coating types and Applications, including industrial tools, electronic components and high-performance coating equipment. It provides a scientific basis for the development, quality control and performance optimization of ceramic coatings, which helps to improve the Reliability and suitability of products.
